Yes, I need to find my spare filling neck and send it off to Craig to modify. Maybe today. Until then I've been able to fill Shag with the minimal amount of spillage by (as suggested by JeffTepper), with the pump on my left side, enter the filler neck from a 9 o'clock direction. Starts off with a little spillage but after I twist the nozzle a couple degrees I'm able to fill all the way. Watch next time it wont work......
Due the the depth of the taillight panel as compared to the position of the bumpers, the 65/66's are the easiest to fill with the nozzle in the normal 6 o'clock positon. 67/68's are much more difficult and if you have the finned taillight panels or a flip gas cap it get's more difficult.
